# Can I keep my backups on the same external drive I move files to?

You can back up **internal** folders to it, and that still protects them against mistakes and against your Mac's own disk failing. But don't use it as the backup destination for the fast drive's own contents — the files you moved there would then live on the same drive as their backup.

For what's on the fast drive, give the built-in **Fast drive working set** a different destination: another drive or a cloud account.
